Abstract: A control cable quick release device for use with cable-actuated brake arms that permits disengagement of the control cable from the brake arm without braking the seal between the quick release device and the deformable bellows thereby preventing premature corrosion of the control cable and permitting quick and easy removal of the bicycle wheel.

Abstract: A parallel-push brake assembly for bicycles that provides substantially translational motion of the brake pad using a mechanism that is relatively free of tolerance build-up or slop.

Abstract: A bicycle braking system for permitting controlled rotation and continuous power to the wheels of a bicycle during braking of the bicycle to enhance control of the bicycle during braking includes a cylindrical brake pad that is spring loaded within angled slots in a casing. The brake pad is positioned proximate the rim of a wheel and a cable assembly is coupled to the brake pad for urging the brake pad towards an end of the angled slots and against the rim of the wheel to slow rotation of the wheel.

Abstract: In a brake caliper for a bicycle disk brake, a crank lever is driven to pull two cam shafts in achieving a braking operation, the crank lever having a substantially U-shaped head fastened to the brake cable of the bicycle, two arms respectively coupled to the two cam shafts, two shoulders respectively connected between the arms and two opposite ends of the U-shaped head, a screw hole and a recessed locating hole respectively provided at the shoulders, a screw rod threaded into the screw hole and having one end inserted into the recessed locating hole, and an adjustment nut threaded onto the screw rod and rotated to adjust the pitch between the shoulders of the crank lever.

Abstract: A piston (1) slidably mounted in a case (14), with an actuator cable (22) routed around a first cable guide (15) on the brake case, thence beside the piston to a second cable guide (6) on the end of the piston, which redirects it 180 degrees to return beside the piston to a cable end holder (12) on the case. The actuator cable runs parallel to the piston on both sides, transferring twice its tension to the piston. A cam (60) is provided for full control of the brake gain relative to the tension of the main cable from the hand lever. This adapts the brake to a given hand lever, and provides both fast braking response and high power via a variable gain curve on each stroke. Floating pads are provided for automatic toe. All brake position adjustments relative to the rim are easy and are independent of each other. Quick means are provided for changing the tire and pads, and these operations do not reset the brake position adjustments.

Abstract: A balanced braking system to be used on a bicycle with a front brake and a rear brake, the balanced braking system comprising: a connecting unit, having a driving element, which is driven by the primary cables and carries a contact element; and a secondary cable, having two ends that connect the front and rear brakes and a middle part that runs over the contact element with little friction, revolving the contact element or gliding thereon. When the primary cables are pulled on, the secondary cable is moved aside by the driving element, in turn pulling on the front and rear brakes. Any different forces on the front brake and the rear brake are compensated by the secondary cable. Two guiding elements lead the secondary cable to the contact element from two sides, such that wear on the secondary cable is reduced.
